Third entry in the comedy series is a rote, unfunny exercise

Rather than devoting time to tracking what could have been the comic evolution of the relationship between male nurse Greg Focker (Ben Stiller) and his former CIA agent father-in-law Frank (Robert De Niro), director Paul Weitz seemingly ended up dangling money before his performers to get them to react on cue in this rote, terribly unfunny exercise. Grade: D-.
